A new manufacturer might have resolved the battery problem for Apple’s upcoming iPhone 6 handset.

Per Taiwan’s Economic Daily News and GforGames, Taiwan-based Simplo Technologies is said to have been able to craft batteries thin and flexible enough for the so-called “iPhone 6,” a feat apparently not able to be matched by current suppliers Samsung and LG Chemical.

Reports that Apple’s new 5.5-inch “phablet” may be delayed first surfaced in April. The device’s design is said to call for a battery less than 2 millimeters tall, a significant reduction from the current generation.

Apple is widely expected to debut two new iPhone models this fall, both with displays larger than the current 4-inch unit found on the iPhone 5 series. The new handsets are also rumored to bring an “A8″ application processor and a sapphire-covered display, though the latter is a hotly-debated prediction.
